The COVID-19 pandemic took the entire world by surprise. One of the most needed items in hospitals on the frontlines is personal protective equipment (PPE), including surgical masks. The melt-blown fabric used for medical surgical masks is created by blowing hot compressed purified air. Brazed plate heat exchangers (BPHE´s) like those produced by SWEP, serves as the main component to exchange heat in the production equipment and its accurate performance assure the functional stability of the masks.
